Note
The terms “Unidirectional Path Switched Ring” and “UPSR” may appear in Cisco literature. These terms
do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration.
Rather, these terms, as well as “Path Protected Mesh Network” and “PPMN,” refer generally to Cisco’s
path protection feature, which may be used in any topological network configuration. Cisco does not
recommend using its path protection feature in any particular topological network configuration.
This chapter describes the Cisco ONS 15454 optical card features and functions. It includes descriptions,
hardware specifications, and block diagrams for each optical card. For installation and card turn-up
procedures, refer to the Cisco ONS 15454 Procedure Guide.

Optical Cards
Optical Card Overview
Corning MetroCor fiber is optimized for optical interfaces that transmit at 1550 nm or in the C and L
DWDM windows, and targets interfaces with higher dispersion tolerances than those found in
OC3 IR/STM1 SH, OC12 IR/STM4 SH, and OC48 IR/STM16 SH interface optics. If you are using
Corning MetroCor fiber, OC3 IR/STM1 SH, OC12 IR/STM4 SH, and OC48 IR/STM16 SH interface
optics become dispersion limited before they become attenuation limited. In this case, consider using
OC12 LR/STM4 LH and OC48 LR/STM16 LH cards instead of OC12 IR/STM4 SH and OC48
IR/STM16 SH cards.
With all fiber types, network planners/engineers should review the relative fiber type and optics
specifications to determine attenuation, dispersion, and other characteristics to ensure appropriate
deployment.

OC3 IR 4/STM1 SH 1310 Card
You can install the OC3 IR 4/STM1 SH 1310 card in Slots 1 to 6 and 12 to 17. The card can be
provisioned as part of a path protection or in a linear add/drop multiplexer (ADM) configuration. Each
interface features a 1310-nm laser and contains a transmit and receive connector (labeled) on the card
faceplate. The card uses SC connectors.
The OC3 IR 4/STM1 SH 1310 card supports 1+1 unidirectional or bidirectional protection switching.
You can provision protection on a per port basis.
The OC3 IR 4/STM1 SH 1310 card detects loss of signal (LOS), loss of frame (LOF), loss of pointer
(LOP), line-layer alarm indication signal (AIS-L), and line-layer remote defect indication (RDI-L)
conditions. Refer to the Cisco ONS 15454 Troubleshooting Guide for a description of these conditions.
The card also counts section and line bit interleaved parity (BIP) errors.
To enable automatic protection switching (APS), the OC3 IR 4/STM1 SH 1310 card extracts the K1 and
K2 bytes from the SONET overhead to perform appropriate protection switches. The data
communication channel/general communication channel (DCC/GCC) bytes are forwarded to the
TCC2/TCC2P card, which terminates the DCC/GCC.
4.2.1 OC3 IR 4/STM1 SH 1310 Card-Level Indicators
Table 4-3 describes the three card-level LED indicators on the OC3 IR 4/STM1 SH 1310 card.

overhead and processes them to switch accordingly. The DCC/GCC bytes are forwarded to the
TCC2/TCC2P card, which terminates the DCC/GCC.
Note
If you ever expect to upgrade an OC-12/STM-4 ring to a higher bit rate, you should not put an
OC12 IR/STM4 SH 1310-4 card in that ring. The four-port card is not upgradable to a single-port card.
The reason is that four different spans, possibly going to four different nodes, cannot be merged to a
single span.

1542.14 nm, 1542.94 nm, 1543.73 nm, and 1544.53 nm). ITU spacing conforms to ITU-T G.692 and
Telcordia GR-2918-CORE, Issue 2.
The other 18 cards operate in the red band with spacing of 100 GHz on the ITU grid (1546.12 nm,
1546.92 nm, 1547.72 nm, 1548.51 nm,1549.32 nm, 1550.12 nm, 1550.92 nm, 1551.72 nm, 1552.52 nm,

1559.79 nm, and 1560.61 nm). These cards are also designed to interoperate with the Cisco ONS 15216
DWDM solution.
You can install the OC48 ELR/STM16 EH 100 GHz cards in Slots 5, 6, 12, and 13 and provision the card
as a drop or span card in a two-fiber or four-fiber BLSR, path protection, or ADM (linear) configuration.
Each OC48 ELR/STM16 EH 100 GHz card uses extended long-reach optics operating individually
within the ITU-T 100-GHz grid. The OC-48 DWDM cards are intended to be used in applications with
long unregenerated spans of up to 300 km (186 miles) (with mid-span amplification). These transmission
distances are achieved through the use of inexpensive optical amplifiers (flat gain amplifiers) such as
Cisco ONS 15216 erbium-doped fiber amplifiers (EDFAs).
Maximum system reach in filterless applications is 26 dB without the use of optical amplifiers or
regenerators. However, system reach also depends on the condition of the facilities, number of splices
and connectors, and other performance-affecting factors. When used in combination with ONS 15216

Caution
You must use a 19 to 24 dB (14 to 28 dB for 15454-OC192-LR2) (20 dB recommended) fiber attenuator
when connecting a fiber loopback to an OC192 LR/STM64 LH 1550 card. Never connect a direct fiber
loopback. Using fiber loopbacks causes irreparable damage to the card. A transmit-to-receive (Tx-to-Rx)
connection that is not attenuated damages the receiver.
You can install OC192 LR/STM64 LH 1550 cards in Slots 5, 6, 12, and 13 and provision the card as a
drop or span card in a two-fiber or four-fiber BLSR, path protection, ADM (linear) configuration, or as
a regenerator for longer span reaches.

OC192 LR/STM64 LH ITU 15xx.xx Card
The OC-192 card port features a 1550-nm laser and contains a transmit and receive connector (labeled)
on the card faceplate.
The card uses a dual SC connector for optical cable termination. The card supports 1+1 unidirectional
and bidirectional facility protection. It also supports 1:1 protection in four-fiber bidirectional line
switched ring applications where both span switching and ring switching might occur.
The OC192 LR/STM64 LH 1550 card detects SF, LOS, or LOF conditions on the optical facility. The
card also counts section and line BIT errors from B1 and B2 byte registers in the section and line
overhead.

Description
Red FAIL LED
The red FAIL LED indicates that the card’s processor is not ready. Replace
the card if the red FAIL LED persists.
ACT/STBY LED
If the ACT/STBY LED is green, the card is operational and ready to carry
traffic. If the ACT/STBY LED is amber, the card is operational and in
standby (protect) mode or is part of an active ring switch (BLSR).
Green (Active)
Amber (Standby)
Amber SF LED
The amber SF LED indicates a signal failure or condition such as LOS, LOF,
or high BERs on the card’s port. The amber SF LED is also on if the transmit
and receive fibers are incorrectly connected. If the fibers are properly
connected, the light turns off.
4.16.2 OC192 LR/STM64 LH 1550 Port-Level Indicators
You can find the status of the OC192 LR/STM64 LH 1550 card port using the LCD screen on the
ONS 15454 fan-tray assembly. Use the LCD to view the status of the port or card slot; the screen displays
the number and severity of alarms for a given port or slot.
Note
The optical output power of the OC192 LR/STM64 LH 1550 (+4 dBm to +7 dBm) is 6 dB lower than in
L-64.2b of the 10/2000 prepublished unedited version of ITU-T G.691 (+10 dBm to +13 dBm). However,
the total attenuation range of the optical path, 22 to 16 dB, is maintained by the optical receiver
sensitivity range of the OC192 LR/STM64 LH 1550 (–7 dBm to –24 dBm). This sensitivity range
outperforms the specification in L-64.2b of the 10/2000 prepublished unedited version of ITU-T G.691
as the resulting link budget of the card is 26 dBm .
4.17 OC192 LR/STM64 LH ITU 15xx.xx Card
Sixteen distinct OC-192/STM-64 ITU 100 GHz DWDM cards comprise the ONS 15454 DWDM channel
plan. Each OC192 LR/STM64 LH ITU 15xx.xx card provides one long-reach STM-64/OC-192 port per
card, compliant with ITU-T G.707, ITU-T G.957, and Telcordia GR-253-CORE (except minimum and
